Dear

Shareholders,

Inflation

concerns

have

continued

to

dominate

the

investment

landscape

in

2023.

Inflation

rates

have

fallen

meaningfully

from

post-pandemic

highs,

helped

by

the

significant

policy

interest

rate

increases

from

the

U.S.

Federal

Reserve

(Fed)

and

other

global

central

banks

since

2022

and

the

normalization

of

supply

chains.

However,

they

currently

remain

above

the

levels

that

central

banks

consider

supportive

of

their

economies’

long-term

growth.

Core

inflation

measures,

which

exclude

volatile

food

and

energy

prices,

in

particular

remain

above

central

banks’

targeted

levels.

At

the

same

time,

the

U.S.

economy

has

remained

relatively

resilient,

while

stubbornly

high

inflation

and

tighter

financial

conditions

are

beginning

to

slow

the

U.K.

and

European

economies.

U.S.

gross

domestic

product

rose

4.9%

in

the

third

quarter

of

2023,

2.1%

in

the

second

quarter

of

2023

and

2.0%

in

the

first

quarter

of

2023,

after

growing

2.1%

in

2022

overall

compared

to

2021.

Consider

that

much

of

this

growth

occurred

while

the

Fed

was

raising

interest

rates

in

one

of

the

fastest

hiking

cycles

in

its

history.

The

Fed

increased

the

target

fed

funds

rate

from

near

zero

in

March

2022

to

a

range

of

5.25%

to

5.50%

as

of

November

2023,

with

pauses

in

June

2023,

September

2023

and

November

2023.

Despite

historically

high

inflation

and

rapidly

rising

interest

rates,

the

jobs

market

has

remained

relatively

strong,

helping

to

support

consumer

sentiment

and

spending.

However,

markets

are

concerned

that

these

conditions

could

keep

upward

pressure

on

prices

and

wages,

leading

to

interest

rates

staying

higher

for

longer

and

a

potentially

deeper

slowdown

in

the

economy.

U.S.

regional

banks

–

after

enduring

the

relatively

contained

collapses

of

Silicon

Valley

Bank,

Signature

Bank

and

First

Republic

Bank

and

major

European

bank

Credit

Suisse

in

March

2023

–

remain

exposed

to

challenges

in

the

commercial

real

estate

sector.

Additionally,

concerns

about

government

funding

and

deficits

persist.

Congress

averted

a

near-term

default

scenario

in

June

2023

and

partial

government

shutdowns

in

September

and

November

2023,

but

funding

will

need

to

be

renegotiated

again

in

January

and

February

2024.

Given

the

lingering

upside

risks

to

inflation

and

the

lagging

impact

of

tighter

credit

conditions

on

the

economy,

Fed

officials

are

closely

monitoring

incoming

inflation

data

and

other

economic

measures

to

modify

their

rate

setting

activity

based

upon

these

factors

on

a

meeting-by-meeting

basis.

The

Fed

remains

committed

to

acting

until

it

sees

sustainable

progress

toward

its

inflation

goals.

In

the

meantime,

markets

are

likely

to

continue

reacting

in

the

short

term

to

news

about

inflation

data,

economic

indicators

and

central

bank

policy.

We

encourage

investors

to

keep

a

long-term

perspective

amid

the

short-term

turbulence.

Your

financial

professional

can

help

you

review

how

well

your

portfolio

is

aligned

with

your

time

horizon,

risk

tolerance

and

investment

goals.

On

behalf

of

the

other

members

of

the

Nuveen

Fund

Board,

we

look

forward

to

continuing

to

earn

your

trust

in

the

months

and

years

ahead.

COMMON

DISTRIBUTION

INFORMATION

The

following

information

regarding the

Funds' distributions

is

current

as

of

September

30,

2023.  Each

Fund's

distribution

levels

may

vary

over

time

based

on each

Fund's

investment

activity

and

portfolio

investment

value

changes.

During

the

current

reporting

period, each

Fund's

distributions

to

common

shareholders

were

as

shown

in

the

accompanying

table.

Each

Fund

seeks

to

pay

regular

monthly

dividends

out

of

its

net

investment

income

at

a

rate

that

reflects

its

past

and

projected

net

income

performance.

To

permit

each

Fund

to

maintain

a

more

stable

monthly

dividend,

the

Fund

may

pay

dividends

at

a

rate

that

may

be

more

or

less

than

the

amount

of

net

income

actually

earned

by

the

Fund

during

the

period.

Distributions

to

common

shareholders

are

determined

on

a

tax

basis,

which

may

differ

from

amounts

recorded

in

the

accounting

records.

In

instances

where

the

monthly

dividend

exceeds

the

earned

net

investment

income,

the

Fund

would

report

a

negative

undistributed

net

ordinary

income.

Refer

to the

Notes

to

Financial Statements for

additional

information

regarding

the

amounts

of

undistributed

net

ordinary

income

and

undistributed

net

long-term

capital

gains

and

the

character

of

the

actual

distributions

paid

by

the

Fund

during

the

period.

All

monthly

dividends

paid

by

each

Fund

during

the

current

reporting

period

were

paid

from

net

investment

income.

If

a

portion

of

the

Fund’s

monthly

distributions

is

sourced

or

comprised

of

elements

other

than

net

investment

income,

including

capital

gains

and/

or

a

return

of

capital,

shareholders

will

be

notified

of

those

sources.

For

financial

reporting

purposes,

the

per

share

amounts

of

each

Fund’s

distributions

for

the

reporting

period

are

presented

in

this

report’s

Financial

Highlights.

For

income

tax

purposes,

distribution

information

for

each

Various

funds

and

accounts

managed

by

Nuveen,

including

the

Fund,

collectively

are

a

substantial

minority

holder

of

ENGH’s

outstanding

shares

of

common

stock,

and

possess

certain

other

rights

with

respect

to

the

corporate

governance

of

ENGH.

Due

to

these

facts,

under

the

federal

securities

laws,

the

securities

of

ENGH

held

by

Nuveen

funds

and

accounts,

including

the

Fund,

cannot

be

sold

except

under

limited

conditions

(which

are

not  currently

satisfied).

The

Fund

is

therefore

unable

to

sell

such

shares

in

ordinary

secondary

market

transactions

at

this

time.

On

March

6,

2023

Vistra

Corp.

(“Vistra”)

announced

that

it

has

executed

a

definitive

agreement

with

Energy

Harbor

Corp.,

pursuant

to

which

Energy

Harbor

will

merge

with

and

into

a

newly-formed

subsidiary

of

Vistra.  The

companies

anticipate

closing

the

transaction

in

the

fourth

quarter

of

2023.  In

connection

with

the

transaction,

Nuveen

funds

and

accounts

expect

to

receive

a

combination

of

cash

and

shares

in

a

newly

formed

entity.

Nuveen

expects

these

shares

to

be

issued

in

a

private

transaction

and

may

have

reduced

secondary

market

liquidity.  The

transaction

is

subject

to

certain

regulatory

approvals

and

there

can

be

no

assurance

that

the

transaction

will

close.

(f)

Non-income

not

declared

(g)

of

greater

than

one

year,

but

has

variable

rate

and/or

features

which

qualify

it

as

a

short-term

investment.

The

rate

disclosed,

as

well

as

the

reference

rate

and

spread,

where

applicable,

is

that

in

effect

as

of

the

end

of

the

reporting

period.

This

changes

periodically

based

on

market

conditions

or

Developments

Regarding

the

Funds’

Control

Share

By-Law:

On

October

5,

2020,

the

Funds

and

certain

other

closed-end

funds

in

the

Nuveen

fund

complex

amended

their

by-laws.

Among

other

things,

the

amended

by-laws

included

provisions

pursuant

to

which,

in

summary,

a

shareholder

who

obtains

beneficial

ownership

of

common

shares

in

a

Control

Share

Acquisition

(as

defined

in

the

by-laws)

shall

have

the

same

voting

rights

as

other

common

shareholders

only

to

the

extent

authorized

by

the

other

disinterested

shareholders

(the

“Control

Share

By-Law”).

On

January

14,

2021,

a

shareholder

of

certain

Nuveen

closed-end

funds

filed

a

civil

complaint

in

the

U.S.

District

Court

for

the

Southern

District

of

New

York

(the

“District

Court”)

against

certain

Nuveen

funds

and

their

trustees,

seeking

a

declaration

that

such

funds’

Control

Share

By-Laws

violate

the

1940

Act,

rescission

of

such

fund’s

Control

Share

By-Laws

and

a

permanent

injunction

against

such

funds

applying

the

Control

Share

By-Laws.

On

February

18,

2022,

the

District

Court

granted

judgment

in

favor

of

the

plaintiff’s

claim

for

rescission

of

such

funds’

Control

Share

By-Laws

and

the

plaintiff’s

declaratory

judgment

claim,

and

declared

that

such

funds’

Control

Share

By-Laws

violate

Section

18(i)

of

the

1940

Act.

Following

review

of

the

judgment

of

the

District

Court,

on

February

22,

2022,

the

Board

of

Trustees

(the

“Board”)

amended

the

Funds’

by-laws

to

provide

that

the

Funds’

Control

Share

By-Law

shall

be

of

no

force

and

effect

for

so

long

as

the

judgment

of

the

District

Court

is

effective

and

that

if

the

judgment

of

the

District

Court

is

reversed,

overturned,

vacated,

stayed,

or

otherwise

nullified,

the

Funds’

Control

Share

By-Law

will

be

automatically

reinstated

and

apply

to

any

beneficial

owner

of

common

shares

acquired

in

a

Control

Share

Acquisition,

regardless

of

whether

such

Control

Share

Acquisition

occurs

before

or

after

such

reinstatement,

for

the

duration

of

the

stay

or

upon

issuance

of

the

mandate

reversing,

overturning,

vacating

or

otherwise

nullifying

the

judgment

of

the

District

Court.

On

February

25,

2022,

the

Board

and

the

Funds

appealed

the

District

Court’s

decision

to

the

U.S.

Court

of

Appeals

for

the

Second

Circuit.

Actual

results

may

differ

from

those

estimates. Each

Fund

is

an

investment

company

and

follows

accounting

guidance

in

the

Financial

Accounting

Standards

Board

(“FASB”)

Accounting

Standards

Codification

946,

Financial

Services

–

Investment

Companies.

The

net

asset

value

(“NAV”)

for

financial

reporting

purposes

may

differ

from

the

NAV

for

processing

security

and

shareholder

transactions.

The

NAV

for

financial

reporting

purposes

includes

security

and

shareholder

transactions

through

the

date

of

the

report.

Total

return

is

computed

based

on

the

NAV

used

for

processing

security

and

shareholder

transactions.

The

following

is

a

summary

of

the

significant

accounting

policies

consistently

followed

by

the

Funds.

Compensation:

The

Funds pay

no

compensation

directly

to

those

of its

officers,

all

of

whom

receive

remuneration

for

their

services

to

the

Funds

from

the

Adviser

or

its

affiliates.

The Board has

adopted

a

deferred

compensation

plan

for

independent

trustees

that

enables

trustees

to

elect

to

defer

receipt

of

all

or

a

portion

of

the

annual

compensation

they

are

entitled

to

receive

from

certain

Nuveen-advised

funds.

Under

the

plan,

deferred

amounts

are

treated

as

though

equal

dollar

amounts

had

been

invested

in

shares

of

select

Nuveen-advised

funds.

Custodian

Fee

Credit:

As

an

alternative

to

overnight

investments,

each

Fund

has

an

arrangement

with

its

custodian

bank,

State

Street

Bank

and

Trust

Company,

(the

“Custodian”)

whereby

certain

custodian

fees

and

expenses

are

reduced

by

net

credits

earned

on

each

Fund’s

cash

on

deposit

with

the

bank.

Credits

for

cash

balances

may

be

offset

by

charges

for

any

days

on

which

a

Fund

overdraws

its

account

at

the

Custodian.

The

amount

of

custodian

fee

credit

earned

by

a

Fund

is

recognized

on

the

Statement

of

Operations

as

a

component

of

“Custodian

expenses,

net.”

During

the

current

reporting

period,

the

custodian

fee

credit

earned

by

each

Fund

was

as

follows:

61

Distributions

to

Common

Shareholders:

Distributions

to

common shareholders

are

recorded

on

the

ex-dividend

date.

The

amount,

character

and

timing

of

distributions

are

determined

in

accordance

with

federal

income

tax

regulations,

which

may

differ

from

U.S.

GAAP.

Indemnifications:

Under

the

Funds'

organizational

documents, their

officers

and

trustees

are

indemnified

against

certain

liabilities

arising

out

of

the

performance

of

their

duties

to

the

Funds.

In

addition,

in

the

normal

course

of

business,

the Funds

enter

into

contracts

that

provide

general

indemnifications

to

other

parties.

The

Funds'

maximum

exposure

under

these

arrangements

is

unknown

as

this

would

involve

future

claims

that

may

be

made

against

the Funds

that

have

not

yet

occurred.

However,

the Funds

have

not

had

prior

claims

or

losses

pursuant

to

these

contracts

and

expects

the

risk

of

loss

to

be

remote.

Investments

and

Investment

Income:

Securities

transactions

are

accounted

for

as

of

the

trade

date

for

financial

reporting

purposes.

Realized

gains

and

losses

on

securities

transactions

are

based

upon

the

specific

identification

method.

Investment

income

is

comprised

of

interest

income,

which

is

recorded

on

an

accrual

basis

and

includes

accretion

of

discounts

and

amortization

of

premiums

for

financial

reporting

purposes.

Investment

income

also

reflects

payment-in-kind

(“PIK”)

interest

and

paydown

gains

and

losses,

if

any.

PIK

interest

represents

income

received

in

the

form

of

securities

in

lieu

of

cash.

Investment

income

also

reflects

dividend

income,

which

is

recorded

on

the

ex-dividend

date.

Netting

Agreements:

In

the

ordinary

course

of

business,

the

Funds

may

enter

into

transactions

subject

to

enforceable

International

Swaps

and

Derivatives

Association,

Inc.

(ISDA)

master

agreements

or

other

similar

arrangements

(“netting

agreements”).

Generally,

the

right

to

offset

in

netting

agreements

allows

each

Fund

to

offset

certain

securities

and

derivatives

with

a

specific

counterparty,

when

applicable,

as

well

as

any

collateral

received

or

delivered

to

that

counterparty

based

on

the

terms

of

the

agreements.

Generally,

each

Fund

manages

its

cash

collateral

and

securities

collateral

on

a

counterparty

basis.

With

respect

to

certain

counterparties,

in

accordance

with

the

terms

of

the

netting

agreements,

collateral

posted

to

the

Funds

is

held

in

a

segregated

account

by

the

Funds’

custodian

and/or

with

respect

to

those

amounts

which

can

be

sold

or

repledged,

are

presented

in

the

Funds’

Portfolio

of

Investments

or

Statement

of

Assets

and

Liabilities.

The

Funds’

investments

subject

to

netting

agreements

as

of

the

end

of

the

reporting

period,

if

any,

are

further

described

later

in

these

Notes

to

Financials.

New

Accounting

Pronouncement: 

In

March

2020,

FASB

issued

Accounting

Standards

Update

("ASU")

2020-04,

Reference

Rate

Reform:

Facilitation

of

the

Effects

of

Reference

Rate

Reform

on

Financial

Reporting.

The

main

objective

of

the

new

guidance

is

to

provide

relief

to

companies

that

will

be

impacted

by

the

expected

change

in

benchmark

interest

rates,

when

participating

banks

will

no

longer

be

required

to

submit

London

Interbank

Offered

Rate

(LIBOR)

quotes

by

the

UK

Financial

Conduct

Authority

(FCA).

The

new

guidance

allows

companies

to,

provided

the

only

change

to

existing

contracts

are

a

change

to

an

approved

benchmark

interest

rate,

account

for

modifications

as

a

continuance

of

the

existing

contract

without

additional

analysis.

For

new

and

existing

contracts,

the

Funds

may

elect

to

apply

the

amendments

as

of

March

12,

2020

through

December

31,

2022.

In

December

2022,

FASB

deferred

ASU

2022-04

and

issued

ASU

2022-06,

Reference

Rate

Reform:

Deferral

of

the

Sunset

Date

of

Topic

848,

which

extends

the

application

of

the

amendments

through

December

31,

2024.

Management

has

not

yet

elected

to

apply

the

amendments,

is

continuously

evaluating

the

potential

effect

a

discontinuation

of

LIBOR

could

have

on

the

Funds’

investments

and

has

currently

determined

that

it

is

unlikely

the

ASU’s

adoption

will

have

a

significant

impact

on

the

Funds’

financial

statements

and

various

filings.

New

Accounting

Pronouncement:

In

June

2022,

the

FASB

issued

ASU

2022-03

to

clarify

the

guidance

in

Topic

820,

Fair

Value

Measurement

("Topic

820").

The

amendments

in

ASU

2022-03

affect

all

entities

that

have

investments

in

equity

securities

measured

at

fair

value

that

are

subject

to

a

contractual

sale

restriction.

ASU

2022-03

(1)

clarifies

the

guidance

in

Topic

820,

when

measuring

the

fair

value

of

an

equity

security

subject

to

contractual

restrictions

that

prohibit

the

sale

of

equity

security,

(2)

amends

a

related

illustrative

example,

and

(3)

introduces

new

disclosure

requirements

for

equity

securities

subject

to

contractual

sale

restrictions

that

are

measured

at

fair

value

in

accordance

with

Topic

820.

For

public

business

entities,

the

amendments

in

ASU

2022-03

are

effective

for

fiscal

years

beginning

after

December

15,

2023,

and

interim

periods

within

those

fiscal

years.

For

all

other

entities,

the

amendments

are

effective

for

fiscal

years

beginning

after

December

15,

2024,

and

interim

periods

within

those

fiscal

years.

Early

adoption

is

permitted

for

both

interim

and

annual

financial

statements

that

have

not

yet

been

issued

or

made

available

for

issuance.

During

the

current

fiscal

period,

the

Funds

adopted

the

new

guidance

and

there

was

no

material

impact

to

the

Funds.

Investment

Valuation

and

Fair

Value

Measurements 

The

Funds’

investments

in

securities

are

recorded

at

their

estimated

fair

value

utilizing

valuation

methods

approved

by

the

Adviser,

subject

to

oversight

of

the Board.

Fair

value

is

defined

as

the

price

that

would

be

received

upon

selling

an

investment

or

transferring

a

liability

in

an

orderly

transaction

to

an

independent

buyer

in

the

principal

or

most

advantageous

market

for

the

investment.

U.S.

GAAP

establishes

the

three-tier

hierarchy

which

is

used

to

maximize

the

use

of

observable

market

data

and

minimize

the

use

of

unobservable

inputs

and

to

establish

classification

of

fair

value

measurements

for

disclosure

purposes.

Observable

inputs

reflect

the

assumptions

market

participants

would

use

in

pricing

the

asset

or

liability.

Observable

inputs

are

based

on

market

data

obtained

from

sources

independent

of

the

reporting

entity.

Unobservable

inputs

reflect

management’s

assumptions

about

the

assumptions

market

participants

would

use

in

pricing

the

asset

or

liability.

Unobservable

inputs

are

based

on

the

best

information

available

in

the

circumstances.

The

following

is

a

summary

of

the

three-tiered

hierarchy

of

valuation

input

levels.

Level

Inputs

are

unadjusted

and

Level

–

Prices

are

determined

using

investments).

A

description

of

the

valuation

techniques

applied

to

the

Funds’

major

classifications

of

assets

and

liabilities

measured

at

fair

value

follows:

Equity

securities

and

exchange-traded

funds

listed

or

traded

on

a

national

market

or

exchange

are

valued

based

on

their

last

reported sales

price

or

official

closing

price of such

market

or

exchange

on

the

valuation

date.

Foreign

equity

securities

and

registered

investment

companies

that

trade

on

a

foreign

exchange

are

valued

at

the

last

reported sales

price

or

official

closing

price

on

the

principal

exchange

where

traded,

and

converted

to

U.S.

dollars

at

the

prevailing

rates

of

exchange

on

the valuation

date.

For

events affecting

the value

of

foreign

securities

between

the

time

when

the

exchange

on

which

they

are

traded

closes

and

the

time

when

the

Funds'

net

assets

are

calculated,

such

securities

will

be

valued

at

fair

value

in

accordance

with

procedures

adopted

by

the

Adviser,

subject

to

the

oversight

of

the

Board. To

the

extent

these

securities

are

actively

traded

and

no

valuation

adjustments

are

applied,

they

are

generally

classified

as

Level

1. When

valuation

adjustments

are

applied

to

the

most

recent

last

sales

price

or

official

closing

price, these

securities

are

generally

classified

as

Level

2.

Prices

of

fixed-income

securities

are

generally

provided

by

pricing

services

approved

by

the

Adviser,

which

is

subject

to

review

by

the

Adviser

and

oversight

of

the

Board. Pricing

services

establish

a

security’s

fair

value

using

methods

that

may

include

consideration

of

the

following:

yields

or

prices

of

investments

of

comparable

quality,

type

of

issue,

coupon,

maturity

and

rating,

market

quotes

or

indications

of

value

from

security

dealers,

evaluations

of

anticipated

cash

flows

or

collateral,

general

market

conditions

and

other

information

and

analysis,

including

the

obligor’s

credit

characteristics

considered

relevant.

In

pricing

certain

securities,

particularly

less

liquid

and

lower

quality

securities,

pricing

services

may

consider

information

about

a

security,

its

issuer

or

market

activity

provided

by

the

Adviser.

These

securities

are

generally

classified

as

Level

2.

For

any

portfolio

security

or

derivative

for

which

market

quotations

are

not

readily

available

or

for

which

the

Adviser

deems

the

valuations

derived

using

the

valuation

procedures

described

above

not

to

reflect

fair

value,

the

Adviser

will

determine

a

fair

value

in

good

faith

using

alternative

procedures

approved

by

the

Adviser,

subject

to

the

oversight

of

the

Board.

As

a

general

principle,

the

fair

value

of

a

security

is

the

amount

that

the

owner

might

reasonably

expect

to

receive

for

it

in

a

current

sale.

A

variety

of

factors

may

be

considered

in

determining

the

fair

value

of

such

securities,

which

may

include

consideration

of

the

following:

yields

or

prices

of

investments

of

comparable

quality,

type

of

issue,

coupon,

maturity

and

rating,

market

quotes

or

indications

of

value

from

security

dealers,

evaluations

of

anticipated

cash

flows

or

collateral,

general

market

conditions

and

other

information

and

analysis,

including

the

obligor’s

credit

characteristics

considered

relevant.

To

the

extent

the

inputs

are

observable

and

timely,

the

values

would

be

classified

as

Level

2;

otherwise

they

would

be

classified

as

Level

3.

The

following

table

summarizes

the

market

value

of

the

Funds’

investments

as

of

the

end

of

the

reporting

period,

based

on

the

inputs

used

to

value

them:

4.

Portfolio

Securities

Inverse

Floating

Rate

Securities:

Each

Fund

is

authorized

to

invest

in

inverse

floating

rate

securities.

An

inverse

floating

rate

security

is

created

by

depositing

a

municipal

bond

(referred

to

as

an

“Underlying

Bond”),

typically

with

a

fixed

interest

rate,

into

a

special

purpose

tender

option

bond

(“TOB”)

trust

(referred

to

as

the

“TOB

Trust”)

created

by

or

at

the

direction

of

one

or

more

Funds.

In

turn,

the

TOB

Trust

issues

(a)

floating

rate

certificates

(referred

to

as

“Floaters”),

in

face

amounts

equal

to

some

fraction

of

the

Underlying

Bond’s

par

amount

or

market

value,

and

(b)

an

inverse

floating

rate

certificate

(referred

to

as

an

“Inverse

Floater”)

that

represents

all

remaining

or

residual

interest

in

the

TOB

Trust.

Floaters

typically

pay

short-term

tax-exempt

interest

rates

to

third

parties

who

are

also

provided

a

right

to

tender

their

certificate

and

receive

its

par

value,

which

may

be

paid

from

the

proceeds

of

a

remarketing

of

the

Floaters,

Provider”),

or

by

the

sale

of

assets

from

the

TOB

Trust.

The

Inverse

Floater

is

issued

to

a

long

term

investor,

such

as

one

or

more

of

the

Funds.

The

income

received

by

the

Inverse

Floater

holder

varies

inversely

with

the

short-term

rate

paid

to

holders

of

the

Floaters,

and

in

most

circumstances

the

Inverse

Floater

holder

bears

substantially

all

of

the

Underlying

Bond’s

downside

investment

risk

and

also

benefits

disproportionately

from

any

potential

appreciation

of

the

Underlying

Bond’s

value.

The

value

of

an

Inverse

Floater

will

be

more

volatile

than

that

of

the

Underlying

Bond

because

the

interest

rate

is

dependent

on

not

only

the

fixed

coupon

rate

of

the

Underlying

Bond

but

also

on

the

short-term

interest

paid

on

the

Floaters,

and

because

the

Inverse

Floater

essentially

bears

the

risk

of

loss

(and

possible

gain)

of

the

greater

face

value

of

the

Underlying

Bond.

The

Inverse

Floater

held

by

a

Fund

gives

the

Fund

the

right

to

(a)

cause

the

holders

of

the

Floaters

to

tender

their

certificates

at

par

(or

slightly

more

than

par

in

certain

circumstances),

and

(b)

have

the

trustee

of

the

TOB

Trust

(the

“Trustee”)

transfer

the

Underlying

Bond

held

by

the

TOB

Trust

to

the

Fund,

thereby

collapsing

the

TOB

Trust.

The

Fund

may

acquire

an

Inverse

Floater

in

a

transaction

where

it

(a)

transfers

an

Underlying

Bond

that

it

owns

to

a

TOB

Trust

created

by

a

third

party

or

(b)

transfers

an

Underlying

Bond

that

it

owns,

or

that

it

has

purchased

in

a

secondary

market

transaction

for

the

purpose

of

creating

an

Inverse

Floater,

to

a

TOB

Trust

created

at

its

direction,

and

in

return

receives

the

Inverse

Floater

of

the

TOB

Trust

(referred

to

as

a

“self-deposited

Inverse

Floater”).

A

Fund

may

also

purchase

an

Inverse

Floater

in

a

secondary

market

transaction

from

a

third

party

creator

of

the

TOB

Trust

without

first

owning

the

Underlying

Bond

(referred

to

as

an

“externally-deposited

Inverse

Floater”).

An

investment

in

a

self-deposited

Inverse

Floater

is

accounted

for

as

a

“financing”

transaction

(i.e.,

a

secured

borrowing).

For

a

self-deposited

Inverse

Floater,

the

Underlying

Bond

deposited

into

the

TOB

Trust

is

identified

in

the

Fund’s

Portfolio

of

Investments

as

“(UB)

–

Underlying

bond

of

an

inverse

floating

rate

trust

reflected

as

a

financing

transaction,”

with

the

Fund

recognizing

as

liabilities,

labeled

“Floating

rate

obligations”

on

the

Statement

of

Assets

and

Liabilities,

(a)

the

liquidation

value

of

Floaters

issued

by

the

TOB

Trust,

and

(b)

the

amount

of

any

borrowings

by

the

TOB

Trust

from

a

Liquidity

Provider

to

enable

the

TOB

Trust

to

purchase

outstanding

Floaters

in

lieu

of

a

remarketing.

In

addition,

the

Fund

recognizes

in

“Investment

Income”

the

entire

earnings

of

the

Underlying

Bond,

and

recognizes

(a)

the

interest

paid

to

the

holders

of

the

Floaters

or

on

the

TOB

Trust’s

borrowings,

and

(b)

other

expenses

related

to

remarketing,

administration,

trustee,

liquidity

and

other

services

to

a

TOB

Trust,

as

a

component

of

“Interest

expense”

on

the

Statement

of

Operations.

Earnings

due

from

the

Underlying

Bond

and

interest

due

to

the

holders

of

the

Floaters

as

of

the

end

of

the

reporting

period

are

recognized

as

components

of

“Receivable

for

interest”

and

“Payable

for

interest”

on

the

Statement

of

Assets

and

Liabilities,

respectively.

In

contrast,

an

investment

in

an

externally-deposited

Inverse

Floater

is

accounted

for

as

a

purchase

of

the

Inverse

Floater

and

is

identified

in

the

Fund’s

Portfolio

of

Investments

as

“(IF)

–

Inverse

floating

rate

investment.”

For

an

externally-deposited

Inverse

Floater,

a

Fund’s

Statement

of

Assets

and

Liabilities

recognizes

the

Inverse

Floater

and

not

the

Underlying

Bond

as

an

asset,

and

the

Fund

does

not

recognize

the

Floaters,

or

any

related

borrowings

from

a

Liquidity

Provider,

as

a

liability.

Additionally,

the

Fund

reflects

in

“Investment

Income”

only

the

net

amount

of

earnings

on

the

Inverse

Floater

(net

of

the

interest

paid

to

the

holders

of

the

Floaters

or

the

Liquidity

Provider

as

lender,

and

the

expenses

of

the

Trust),

and

does

not

show

the

amount

of

that

interest

paid

or

the

expenses

of

the

TOB

Trust

as

described

above

as

interest

expense

on

the

Statement

of

Operations.

Fees

paid

upon

the

creation

of

a

TOB

Trust

for

self-deposited

Inverse

Floaters

and

externally-deposited

Inverse

Floaters

are

recognized

as

part

of

the

cost

basis

of

the

Inverse

Floater

and

are

capitalized

over

the

term

of

the

TOB

Trust.

During

the

current

fiscal

period,

the

Funds

did

not

have

any

transactions

in

self-deposited

Inverse

Floaters

and/or

externally-deposited

Inverse

Floaters. 

Zero

Coupon

Securities:

A

zero

coupon

security

does

not

pay

a

regular

interest

coupon

to

its

holders

during

the

life

of

the

security.

Income

to

the

holder

of

the

security

comes

from

accretion

of

the

difference

between

the

original

purchase

price

of

the

security

at

issuance

and

the

par

value

of

the

security

at

maturity

and

is

effectively

paid

at

maturity.

The

market

prices

of

zero

coupon

securities

generally

are

more

volatile

than

the

market

prices

of

securities

that

pay

interest

periodically.

Investment

Transactions:

Long-term

purchases

and

sales

during

the

current

fiscal

period

were

as

follows:

The

Funds

may

purchase

securities

on

a

when-issued

or

delayed-delivery

basis.

Securities

purchased

on

a

when-issued

or

delayed-delivery

basis

may

have

extended

settlement

periods;

interest

income

is

not

accrued

until

settlement

date.

Any

securities

so

purchased

are

subject

to

market

fluctuation

during

this

period. If

a

Fund

has

outstanding

when-issued/delayed-delivery

purchases

commitments

as

of

the

end

of

the

reporting

period,

such

amounts

are

recognized

on

the

Statement

of

Assets

and

Liabilities.

Market

and

Counterparty

Credit

Risk:

In

the

normal

course

of

business

each

Fund

may

invest

in

financial

instruments

and

enter

into

financial

transactions

where

risk

of

potential

loss

exists

due

to

changes

in

the

market

(market

risk)

or

failure

of

the

other

party

to

the

transaction

to

perform

(counterparty

credit

risk).

The

potential

loss

could

exceed

the

value

of

the

financial

assets

recorded

on

the

financial

statements.

Financial

assets,

which

potentially

expose

each

Fund

to

counterparty

credit

risk,

consist

principally

of

cash

due

from

counterparties

on

forward,

option

and

swap

transactions,

when

applicable.

The

extent

of

each

Fund’s

exposure

to

counterparty

credit

risk

in

respect

to

these

financial

assets

approximates

their

carrying

value

as

recorded

Notes

to

Financial

Statements

(Unaudited)

(continued)

Each

Fund

helps

manage

counterparty

credit

risk

by

entering

into

agreements

only

with

counterparties

the

Adviser

believes

have

the

financial

resources

to

honor

their

obligations

and

by

having

the

Adviser

monitor

the

financial

stability

of

the

counterparties.

Additionally,

counterparties

may

be

required

to

pledge

collateral

daily

(based

on

the

daily

valuation

of

the

financial

asset)

on

behalf

of

each

Fund

with

a

value

approximately

equal

to

the

amount

of

any

unrealized

gain

above

a

pre-determined

threshold.

Reciprocally,

when

each

Fund

has

an

unrealized

loss,

the

Funds

have

instructed

the

custodian

to

pledge

assets

of

the

Funds

as

collateral

with

a

value

approximately

equal

to

the

amount

of

the

unrealized

loss

above

a

pre-determined

threshold.

Collateral

pledges

are

monitored

and

subsequently

adjusted

if

and

when

the

valuations

fluctuate,

either

up

or

down,

by

at

least

the

pre-determined

amount.

Derivative

Investments

In

addition

to

the

inverse

floating

rate

securities

in

which

each

Fund

may

invest,

which

are

considered

portfolio

securities

for

financial

reporting

purposes,

each

Fund

is

authorized

to

invest

in

certain

other

derivative

instruments

such

as

futures,

options

and

swap

contracts.

Each

Fund

limits

its

investments

in

futures,

options

on

futures

and

swap

contracts

to

the

extent

necessary

for

the

Adviser

to

claim

the

exclusion

from

registration

by

the

Commodity

Futures

Trading

Commission

as

a

commodity

pool

operator

with

respect

to

the

Fund.

The

Funds

record

derivative

instruments

at

fair

value,

with

changes

in

fair

value

recognized

on

the

Statement

of

Operations,

where

applicable.

Even

though

the

Funds'

investments

in

derivatives

may

represent

economic

hedges,

they

are

not

considered

to

be

hedge

transactions

for

financial

reporting

purposes.

Although

the

Funds

are

authorized

to

invest

in

derivative

instruments

and

may

do

so

in

the

future,

they

did

make

any

with

the

SEC

authorizing

the

Fund

to

additional

common

shares

through

one

or

more

equity

shelf

programs

(“Shelf

Offering”),

which

became

effective

with

the

SEC

during

prior

fiscal

periods.

Under

this

Shelf

varying

amounts

and

by

In

the

event

the

(Unaudited)

(continued)

The

annual

complex-level

fee,

payable

monthly,

for

each

Fund

is

calculated

by

multiplying

the

current

complex-wide

fee

rate,

determined

according

to

the

following

schedule

by

the

Fund’s

daily

managed

assets:

*

For

the

complex-level

fees,

managed

assets

include

closed-end

fund

assets

managed

by

the

Adviser

that

are

attributable

to

certain

types

of

leverage.

For

these

purposes,

leverage

includes

the

funds’

use

of

preferred

stock

and

borrowings

and

certain

investments

in

the

residual

interest

certificates

(also

called

inverse

floating

securities)

in

tender

option

bond

(TOB)

trusts,

including

the

held

by

a

trust

that

has

been

effectively

financed

by

the

trust’s

issuance

of

floating

securities,

subject

to

an

agreement

by

the

Adviser

as

to

certain

funds

to

limit

the

amount

of

such

assets

for

determining

managed

assets

in

certain

circumstances.

The

complex-level

fee

is

calculated

based

upon

the

aggregate

daily

managed

assets

of

all

Nuveen

open-end

and

closed-end

funds

that

constitute

‘’eligible

assets.”

Eligible

assets

do

not

include

attributable

to

or

assets

in

excess

of

a

determined

amount

(originally

$2

billion)

added

to

in

connection

with

the

Adviser’s

assumption

of

the

of

the

former

of

the

during

the

2019

calendar

year.

As

of

September

30,

2023,

the

complex-level

fee

for

each

was

as

follows:

Other

Transactions

with

Affiliates:

Each

Fund

is

permitted

to

purchase

or

sell

securities

from

or

to

certain

other

funds

or

accounts

managed

by

the

Sub-Adviser

(“Affiliated

Entity”)

under

specified

conditions

outlined

in

procedures

adopted

by

the

Board

("cross-trade").

These

procedures

have

been

designed

to

ensure

that

any

cross-trade

of

securities

by

the

Fund

from

or

to

an

Affiliated

Entity

by

virtue

of

having

a

common

investment

adviser

(or

affiliated

investment

adviser),

common

officer

and/or

trustee

complies

with

Rule

17a-7

under

These

transactions

are

effected

at

the

current

market

price

(as

provided

by

an

independent

pricing

service)

without

incurring

broker

commissions.

During

the

the

engaged

in

cross-trades

pursuant

to

these

procedures

as

Borrowing

Arrangements

Committed

Line

of

Credit:

The

Funds,

along

with

certain

other

funds

managed

by

the

Adviser

(“Participating

Funds”),

have

established

a

364-day,

$2.700

billion

standby

credit

facility

with

a

group

of

lenders,

under

which

the

Participating

Funds

may

borrow

for

temporary

purposes

(other

than

on-

going

leveraging

for

investment

purposes).

Each

Participating

Fund

is

allocated

a

designated

proportion

of

the

facility’s

capacity

(and

its

associated

costs,

as

described

below)

based

upon

a

multi-factor

assessment

of

the

likelihood

and

frequency

of

its

need

to

draw

on

the

facility,

the

size

of

the

Fund

and

its

anticipated

draws,

and

the

potential

importance

of

such

draws

to

the

operations

and

well-being

of

the

Fund,

relative

to

those

of

the

other

Funds.

A

Fund

may

effect

draws

on

the

facility

in

excess

of

its

designated

Inter-Fund

Borrowings

and

Lending:

The

SEC

has

granted

an

exemptive

order

permitting

registered

open-end

and

closed-end

Nuveen

funds

to

participate

in

an

inter-fund

lending

facility

whereby

the

Nuveen

funds

may

directly

lend

to

and

borrow

money

from

each

other

for

temporary

purposes

(e.g.,

to

satisfy

redemption

requests

or

when

a

sale

of

securities

“fails,”

resulting

in

an

unanticipated

cash

shortfall)

(the

“Inter-Fund

Program”).

The

closed-end

Nuveen

funds,

including

the

Funds

covered

by

this

shareholder

report,

will

participate

only

as

lenders,

and

not

as

borrowers,

in

the

Inter-Fund

Program

because

such

closed-end

funds

rarely,

if

ever,

need

to

borrow

cash

to

meet

redemptions.

The

Inter-Fund

Program

is

subject

to

a

number

of

conditions,

including,

among

other

things,

the

requirements

that

(1)

no

fund

may

borrow

or

lend

money

through

the

Inter-Fund

Program

unless

it

receives

a

more

favorable

interest

rate

than

is

typically

available

from

a

bank

or

other

financial

institution

for

a

comparable

transaction;

(2)

no

fund

may

borrow

on

an

unsecured

basis

through

the

Inter-Fund

Program

unless

the

fund’s

outstanding

borrowings

from

all

sources

immediately

after

the

inter-fund

borrowing

total

10%

or

less

of

its

total

assets;

provided

that

if

the

borrowing

fund

has

a

secured

borrowing

outstanding

from

any

other

lender,

including

but

not

limited

to

another

fund,

the

inter-fund

loan

must

be

secured

on

at

least

an

equal

priority

basis

with

at

least

an

equivalent

percentage

of

collateral

to

loan

value;

(3)

if

a

fund’s

total

outstanding

borrowings

immediately

after

an

inter-fund

borrowing

would

be

greater

than

10%

of

its

total

assets,

the

fund

may

borrow

through

the

inter-fund

loan

on

a

secured

basis

only;

(4)

no

fund

may

lend

money

if

the

loan

would

cause

its

aggregate

outstanding

loans

through

the

Inter-Fund

Program

to

exceed

15%

of

its

net

assets

at

the

time

of

the

loan;

(5)

a

fund’s

inter-fund

loans

to

any

one

fund

shall

not

exceed

5%

of

the

lending

fund’s

net

assets;

(6)

the

duration

of

inter-

fund

loans

will

be

limited

to

the

time

required

to

receive

payment

for

securities

sold,

but

in

no

event

more

than

seven

days;

and

(7)

each

inter-fund

loan

may

be

called

on

one

business

day’s

notice

by

a

lending

fund

and

may

be

repaid

on

any

day

by

a

borrowing

fund.

In

addition,

a

Nuveen

fund

may

participate

in

the

Inter-Fund

Program

only

if

and

to

the

extent

that

such

participation

is

consistent

with

the

fund’s

investment

objective

and

investment

policies.

The

Board

is

responsible

for

overseeing

the

Inter-Fund

Program.

The

limitations

detailed

above

and

the

other

conditions

of

the

SEC

exemptive

order

permitting

the

Inter-Fund

Program

are

designed

to

minimize

the

risks

associated

with

Inter-Fund

Program

for

both

the

lending

fund

and

the

borrowing

fund.

However,

no

borrowing

or

lending

activity

is

without

risk.

When

a

fund

borrows

money

from

another

fund,

there

is

a

risk

that

the

loan

could

be

called

on

one

day’s

notice

or

not

renewed,

in

which

case

the

fund

may

have

to

borrow

from

a

bank

at

a

higher

rate

or

take

other

actions

to

payoff

such

loan

if

an

inter-fund

loan

is

not

available

from

another

fund.

Any

delay

in

repayment

to

a

lending

fund

could

result

in

a

lost

investment

opportunity

or

additional

borrowing

costs.

During

the

current

reporting

period,

none

of

the

Funds

covered

by

this

shareholder

report

have

entered

into

any

inter-fund

loan

activity.

It

expresses

the

Pre-Refunded

Bond/Pre-Refunding

:

Pre-Refunded

Bond/Pre-Refunding,

also

known

as

advanced

refundings

or

refinancings,

is

a

procedure

used

by

state

and

local

governments

to

refinance

municipal

bonds

to

lower

interest

expenses.

The

issuer

sells

new

bonds

with

a

lower

yield

and

uses

the

proceeds

to

buy

U.S.

Treasury

securities,

the

interest

from

which

is

used

to

make

payments

on

the

higher-yielding

bonds.

Because

of

this

collateral,

pre-refunding

generally

raises

a

bond’s

credit

rating

and

thus

its

value.

At

a

held

on

May

23-25,

2023

(the

“May

Meeting”),

the

Boards

of

Trustees

(collectively,

the

“Board”

and

each

Trustee,

a

“Board

Member”)

of

the

Funds,

which

are

comprised

entirely

of

Board

Members

who

are

not

“interested

persons”

(as

defined

under

the

Investment

Company

Act

of

1940

(the

“1940

Act”))

(the

“Independent

Board

Members”),

approved,

for

their

respective

Fund,

the

renewal

of

the

management

agreement

(each,

an

“Investment

Management

Agreement”)

with

Nuveen

Fund

Advisors,

LLC

(the

“Adviser”)

pursuant

to

which

the

Adviser

serves

as

investment

adviser

to

such

Fund

and

the

sub-advisory

agreement

(each,

a

“Sub-Advisory

Agreement”)

with

Nuveen

Asset

Management,

LLC

(the

“Sub-

Adviser”)

pursuant

to

which

the

Sub-Adviser

serves

as

the

sub-adviser

to

such

Fund

for

an

additional

one-year

term.

As

the

Board

is

comprised

of

all

Independent

Board

Members,

the

references

to

the

Board

and

the

Independent

Board

Members

are

interchangeable.

Following

up

to

an

initial

two-year

period,

the

Board

considers

the

renewal

of

each

Investment

Management

Agreement

and

Sub-Advisory

Agreement

on

behalf

of

the

applicable

Fund

on

an

annual

basis.

The

Investment

Management

Agreements

and

Sub-Advisory

Agreements

are

collectively

referred

to

as

the

“Advisory

Agreements,”

and

the

Adviser

and

the

Sub-Adviser

are

collectively,

the

“Fund

Advisers”

and

each,

a

“Fund

Adviser.”

The

Independent

Board

Members

considered

the

review

of

the

advisory

agreements

for

the

Nuveen

funds

to

be

an

ongoing

process

and

employed

the

accumulated

information,

knowledge

and

experience

the

Board

Members

had

gained

during

their

tenure

on

the

boards

governing

the

Nuveen

funds

and

working

with

the

Adviser

and

the

applicable

sub-advisers

in

their

annual

review

of

the

advisory

agreements.

Throughout

the

year,

the

Board

and

its

committees

meet

regularly

and,

at

these

meetings,

receive

regular

and/or

special

reports

that

cover

an

extensive

array

of

topics

and

information

that

are

relevant

to

the

Board’s

annual

consideration

of

the

renewal

of

the

advisory

agreements

for

the

Nuveen

funds.

Such

information

may

address,

among

other

things,

fund

performance

and

risk

information;

the

Adviser’s

strategic

plans;

product

initiatives

for

various

funds;

the

review

of

the

funds

and

investment

teams;

compliance,

regulatory

and

risk

management

matters;

the

trading

practices

of

the

various

sub-advisers

to

the

Nuveen

funds;

management

of

distributions;

valuation

of

securities;

fund

expenses;

securities

lending;

liquidity

management;

overall

market

and

regulatory

developments;

and

with

respect

to

funds,

capital

management

initiatives,

institutional

ownership,

management

of

leverage

financing

and

the

secondary

market

trading

of

the

closed-end

funds

and

any

actions

to

address

discounts.

The

Board

also

seeks

to

meet

periodically

with

the

Nuveen

funds’

sub-advisers

and/or

portfolio

teams,

when

feasible.

The

presentations,

discussions,

and

meetings

throughout

the

year

also

provide

a

means

for

the

Board

to

evaluate

the

level,

breadth

and

quality

of

services

provided

by

the

Adviser

and

how

such

services

have

changed

over

time

in

light

of

new

or

modified

regulatory

requirements,

changes

to

market

conditions

or

other

factors.

In

connection

with

its

annual

consideration

of

the

advisory

agreements

for

the

Nuveen

funds,

the

Board,

through

its

independent

legal

counsel,

requested

and

received

extensive

materials

and

information

prepared

specifically

for

its

review

of

such

advisory

by

the

and

of

indirect

benefits

received

by

the

Adviser

and

the

sub-advisers

as

a

result

of

their

Nuveen

funds.

The

information

prepared

specifically

for

the

annual

review

supplemented

the

information

provided

to

the

Board

and

its

committees

and

the

evaluations

of

the

Nuveen

funds

by

the

Board

and

its

committees

during

the

year.

The

Board’s

review

of

the

advisory

agreements

for

the

Nuveen

funds

is

based

on

all

the

information

provided

to

the

Board

and

its

committees

throughout

the

year

as

well

as

the

information

prepared

specifically

with

respect

to

the

annual

review

of

such

advisory

agreements.

The

performance,

fee

and

expense

data

and

other

information

provided

by

a

Fund

Adviser,

Broadridge

or

other

service

providers

were

not

independently

verified

by

the

Independent

Board

Members.

As

part

of

its

review,

the

Board

met

on

April

11-12,

2023

(the

“April

Meeting”)

to

review

and

discuss,

in

part,

the

performance

of

the

Nuveen

funds

and

the

Adviser’s

evaluation

of

each

sub-adviser

to

the

Nuveen

funds

and/or

its

investment

teams.

At

the

April

Meeting,

the

Board

Members

asked

questions

and

requested

additional

information

that

was

provided

for

the

May

Meeting.

The

Independent

Board

Members

were

advised

by

independent

legal

counsel

during

the

annual

review

process

as

well

as

throughout

the

year,

including

meeting

in

executive

sessions

with

such

counsel

at

which

no

representatives

from

the

Adviser

or

the

Sub-Adviser

were

present.

In

connection

with

their

annual

review,

the

Independent

Board

Members

also

received

a

memorandum

from

independent

legal

counsel

outlining

their

fiduciary

duties

and

legal

standards

in

reviewing

the

Advisory

Agreements,

including

guidance

from

court

cases

evaluating

advisory

fees.

The

Board’s

decision

to

renew

the

Advisory

Agreements

was

not

based

on

a

single

identified

factor,

but

rather

the

decision

reflected

the

comprehensive

consideration

of

all

the

information

provided

to

the

Board

and

its

committees

throughout

the

year

as

well

as

the

materials

prepared

specifically

in

connection

with

the

renewal

process.

The

contractual

arrangements

are

a

result

of

multiple

years

of

review,

negotiation

and

information

provided

in

connection

with

the

Board’s

annual

review

of

the

Nuveen

funds’

advisory

arrangements

and

oversight

of

the

Nuveen

funds.

Each

Board

Member

may

have

attributed

different

levels

of

importance

to

the

various

factors

and

information

considered

in

connection

with

the

approval

process

and

may

place

different

emphasis

on

the

relevant

information

year

to

year

in

light

of,

among

other

things,

changing

market

and

economic

conditions.

A

summary

of

the

principal

factors

and

information,

but

not

all

the

factors,

the

Board

considered

in

deciding

to

renew

the

Advisory

Agreements

is

set

forth

below.

Annual

Investment

Management

Process

(Unaudited)

(continued)

A.

Nature,

Extent

and

Quality

of

Services

In

evaluating

the

renewal

of

the

Advisory

Agreements,

the

Independent

Board

Members

received

and

considered

information

regarding

the

nature,

extent

and

quality

of

the

applicable

Fund

Adviser’s

services

provided

to

the

respective

Fund

with

particular

focus

on

the

services

and

enhancements

or

changes

to

such

services

provided

during

the

last

year.

The

Independent

Board

Members

considered

the

Investment

Management

Agreements

and

the

Sub-Advisory

Agreements

separately

in

the

course

of

their

review.

With

this

approach,

they

considered

the

respective

roles

of

the

Adviser

and

the

Sub-Adviser

in

providing

services

to

the

Funds.

The

Board

recognized

that

the

Adviser

provides

a

wide

array

of

management,

oversight

and

administrative

services

to

manage

and

operate

the

Nuveen

funds

and

that

the

scope

and

complexity

of

these

services,

along

with

the

undertakings

required

of

the

Adviser

in

connection

with

providing

these

services,

have

expanded

over

time

as

a

result

of,

among

other

things,

regulatory,

market

and

other

developments.

The

Board

noted

the

Adviser’s

dedication

of

resources,

time,

personnel

and

capital

and

commitment

to

continuing

to

develop

improvements

and

innovations

that

seek

to

enhance

the

Nuveen

fund

complex

and

meet

the

needs

of

the

Nuveen

funds

in

an

increasingly

complex

regulatory

environment.

The

Board

received

and

reviewed

information

regarding,

among

other

things,

the

Adviser’s

investment

oversight

responsibilities,

regulatory

and

compliance

services,

administrative

duties

and

other

services.

The

Board

considered

the

breadth

and

the

quality

of

the

services

the

Adviser

and

its

various

teams

provide

in

overseeing

the

investment

management

of

the

Nuveen

funds,

including,

among

other

things,

overseeing

and

reviewing

the

services

provided

by

the

various

sub-advisers

to

the

Nuveen

funds

and

their

investment

teams;

evaluating

fund

performance

and

market

conditions;

overseeing

operational

and

investment

risks;

evaluating

investment

strategies

and

recommending

any

changes

thereto;

managing

liquidity;

managing

the

daily

valuation

of

portfolio

securities;

overseeing

trade

execution

and

securities

lending;

and

setting

and

managing

distributions

consistent

with

the

respective

fund’s

product

design.

With

respect

to

closed-end

funds,

such

services

also

include

managing

leverage;

monitoring

asset

coverage

levels

for

leveraged

funds

and

compliance

with

rating

agency

criteria;

providing

capital

management

and

secondary

market

services

(such

as

implementing

common

share

shelf

offerings,

capital

return

programs

and

common

share

repurchases);

and

maintaining

a

closed-end

fund

investor

relations

program.

The

Board

also

reviewed

the

structure

of

investment

personnel

compensation

of

each

Fund

Adviser

and

considered

whether

the

structure

provides

appropriate

incentives

to

attract

and

maintain

qualified

personnel

and

to

act

in

the

best

interests

of

the

respective

Nuveen

fund.

Given

the

Nuveen

funds

operate

in

a

highly

regulated

industry,

the

Board

further

considered

the

extensive

compliance,

regulatory

and

administrative

services

the

Adviser

and

its

various

teams

provide

to

manage

and

operate

the

Nuveen

funds.

The

Board

recognized

such

services

included,

but

were

not

limited

to,

managing

compliance

policies;

monitoring

compliance

with

applicable

policies,

laws

and

regulations;

devising

internal

compliance

programs

in

seeking

to

enhance

compliance

with

regulatory

requirements

and

creating

a

framework

to

review

and

assess

compliance

programs;

overseeing

sub-adviser

compliance

testing;

preparing

compliance

training

materials;

and

responding

to

regulatory

requests.

The

Board

reviewed

highlights

of

the

various

initiatives

Nuveen

compliance

had

taken

in

2022

including,

among

other

things,

additional

due

diligence

of

service

providers

as

their

operating

environments

evolve

post-Covid

to

more

hybrid

in-person

working

arrangements;

investments

in

supporting

and

expanding

international

trading

capabilities;

continuing

efforts

to

enhance

policies

and

controls

to

address

compliance

risks

including

those

related

to

environmental,

social

and

governance

(“ESG”)

matters

and

new

regulatory

developments

or

guidance;

and

establishing

and

maintaining

compliance

policies

and

comprehensive

compliance

training

programs.

The

Board

also

considered

information

regarding

the

Adviser’s

business

continuity,

disaster

recovery

and

information

security

programs

and

the

periodic

testing

and

review

of

such

programs.

In

addition

to

the

above

functions,

the

Board

considered

the

quality

and

extent

of

other

non-advisory

services

the

Adviser

provides

including,

among

other

things,

various

fund

administration

services

(such

as

preparing,

overseeing

or

assisting

with

the

preparation

of

tax

and

regulatory

filings);

product

management

services

(such

as

evaluating

and

enhancing

products

and

strategies);

legal

support

services;

shareholder

services

and

transfer

agency

function

oversight

services;

and

board

support

and

reporting

services.

With

respect

to

board

support

services,

the

Board

reviewed

a

summary

of

the

annual,

quarterly,

and

special

reports

the

Adviser

and/or

its

affiliates

provided

to

the

Board

throughout

2022.

The

Board

further

acknowledged

various

initiatives

the

Adviser

had

undertaken

or

continued

in

2022

in

seeking

to

improve

the

effectiveness

of

its

organization,

the

Nuveen

funds

product

line-up

as

well

as

particular

Nuveen

fund(s)

through,

among

other

things,

rationalizing

the

product

line

and

gaining

efficiencies

through

mergers,

repositionings

and

liquidations;

launching

new

funds;

reviewing

and

updating

investment

policies

and

benchmarks;

reopening

certain

funds

previously

closed

to

new

investors;

adding

or

modifying

the

share

classes

offered

by

certain

funds;

implementing

fee

waivers

and

expense

cap

changes

for

certain

funds

and

evaluating

and

adjusting

portfolio

management

teams

as

appropriate

for

various

funds;

and

developing

policy

positions

on

a

broad

range

of

regulatory

proposals

that

may

impact

the

funds

and

communicating

with

lawmakers

and

other

regulatory

authorities

to

help

ensure

these

positions

are

represented.

Aside

from

the

services

provided,

the

Board

recognized

the

financial

resources

of

the

Adviser

and

its

affiliates

and

their

willingness

to

make

investments

in

the

technology,

personnel

and

infrastructure

to

support

the

Nuveen

funds,

including

maintaining

a

seed

capital

budget

to

support

new

or

existing

funds

and/or

facilitate

changes

for

a

respective

fund.

The

Board

noted

the

benefits

to

shareholders

of

investing

in

a

fund

that

is

a

part

of

a

large

fund

complex

with

a

variety

of

investment

disciplines,

capabilities,

expertise

and

resources

available

to

navigate

and

support

the

Nuveen

funds

including

during

stressed

times.

The

Board

recognized

the

overall

reputation

and

capabilities

of

the

Adviser

and

its

affiliates,

the

Adviser’s

continuing

commitment

to

provide

high

quality

services,

its

willingness

to

implement

operational

or

organizational

changes

in

seeking,

among

other

things,

to

enhance

efficiencies

and

services

to

the

Nuveen

funds

and

its

responsiveness

to

the

Board’s

questions

and/or

concerns

raised

throughout

the

year

and

during

the

annual

review

of

advisory

agreements.

The

Board

also

considered

the

significant

risks

borne

by

the

Adviser

and

its

affiliates

in

connection

with

their

services

to

the

Nuveen

funds,

including

entrepreneurial

risks

in

sponsoring

new

funds

and

ongoing

risks

with

managing

the

funds

such

as

investment,

operational,

reputational,

regulatory,

compliance

and

litigation

risks.

The

Board

further

considered

the

division

of

responsibilities

between

the

Adviser

and

the

Sub-Adviser

and

recognized

that

the

Sub-Adviser

and

its

investment

personnel

generally

are

responsible

for

the

management

of

each

Fund’s

portfolio

under

the

oversight

of

the

Adviser

and

the

Board.

The

Board

considered

an

analysis

of

the

Sub-Adviser

provided

by

the

Adviser

which

included,

among

other

things,

the

assets

under

management

of

the

applicable

investment

team

and

changes

thereto,

a

summary

of

the

applicable

investment

team

and

changes

to

such

team,

the

investment

process

73

and

philosophy

of

the

applicable

investment

team,

the

performance

of

the

Nuveen

funds

sub-advised

by

the

Sub-Adviser

over

various

periods

of

time

and

a

summary

of

any

significant

policy

and/or

other

changes

to

the

Nuveen

funds

sub-advised

by

the

Sub-Adviser.

The

Board

further

considered

at

the

May

Meeting

or

prior

meetings

evaluations

of

the

Sub-Adviser’s

compliance

programs

and

trade

execution.

The

Board

noted

that

the

Adviser

recommended

the

renewal

of

the

Sub-Advisory

Agreements.

Based

on

its

review,

the

Board

determined,

in

the

exercise

of

its

reasonable

business

judgment,

that

it

was

satisfied

with

the

nature,

extent

and

quality

of

services

provided

to

the

respective

Funds

under

each

applicable

Advisory

Agreement.

B.

The

Investment

Performance

of

the

Funds

and

Fund

Advisers

In

evaluating

the

quality

of

the

services

provided

by

the

Fund

Advisers,

the

Board

also

considered

a

variety

of

investment

performance

data

of

the

Nuveen

funds

prepared

specifically

for

the

annual

review

of

the

advisory

agreements

as

well

as

the

performance

data

the

Board

received

throughout

the

year

representing

different

time

periods.

In

this

regard,

leading

into

the

May

Meeting,

the

Board

reviewed,

among

other

things,

Fund

performance

over

the

quarter,

one-,

three-

and

five-year

periods

ending

December 31,

2022

and

March

31,

2023.

In

addition,

the

Board

reviewed

and

discussed

performance

data

at

its

regularly

scheduled

quarterly

meetings

during

the

year.

The

Board

therefore

took

into

account

the

performance

data,

presentations

and

discussions

(written

and

oral)

that

have

been

provided

for

the

annual

review

as

well

as

in

prior

meetings

over

time

in

evaluating

fund

performance,

including

the

Adviser’s

analysis

of

a

fund’s

performance

with

particular

focus

on

performance

outliers

(both

overperformance

and

underperformance),

the

factors

contributing

to

performance

(including

relative

to

a

fund’s

benchmark

and

peers

and

the

impact

of

market

conditions)

and

any

recommendations

or

steps

that

had

been

taken

or

were

proposed

to

be

taken

to

address

significant

performance

concerns.

In

this

regard,

the

Board

noted,

among

other

things,

that

certain

Nuveen

funds

had

changes

in

portfolio

managers

or

other

significant

changes

to

their

investment

strategies

or

policies

since

March

2020,

and,

as

a

result,

the

Board

reviewed

certain

tracking

performance

data

comparing

the

performance

of

such

funds

before

and

after

such

changes.

The

Board

recognized

that

performance

data

reflects

performance

over

a

specified

period

which

may

differ

significantly

depending

on

the

ending

dates

selected,

particularly

during

periods

of

market

volatility.

Further,

the

Board

noted

that

shareholders

may

evaluate

performance

based

on

their

own

respective

holding

periods

which

may

differ

from

the

performance

periods

reviewed

by

the

Board

and

lead

to

differing

results.

In

its

evaluation,

the

Board

reviewed

Nuveen

fund

performance

results

from

different

perspectives.

In

general,

subject

to

certain

exceptions,

the

Board

reviewed

both

absolute

and

relative

fund

performance

during

the

annual

review

over

the

various

time

periods

and

evaluated

performance

results

in

light

of

a

fund’s

investment

objective(s),

strategies

and

risks.

With

respect

to

the

relative

performance,

the

Board

considered

fund

performance

in

comparison

to

the

performance

of

peer

funds

(the

“Performance

Peer

Group”)

and

recognized

and/or

customized

benchmarks

(i.e.,

generally

benchmarks

derived

from

multiple

recognized

benchmarks).

In

reviewing

such

comparative

performance,

the

Board

was

cognizant

of

the

inherent

limitations

of

such

data

which

can

make

meaningful

performance

comparisons

generally

difficult.

As

an

illustration,

differences

in

the

composition

of

the

Performance

Peer

Group,

the

investment

objective(s),

strategies

and

other

characteristics

of

the

peers

in

the

Performance

Peer

Group,

the

level,

type

and

cost

of

leverage

(if

any)

of

the

peers,

and

the

varying

sizes

of

peers

all

may

contribute

to

differences

in

the

performance

results

of

a

Performance

Peer

Group

compared

to

the

applicable

Nuveen

fund.

With

respect

to

relative

performance

of

a

Nuveen

fund

compared

to

a

benchmark

index,

differences,

among

other

things,

in

the

investment

objective(s)

and

strategies

of

a

fund

and

the

benchmark

(particularly

an

actively

managed

fund

that

does

not

directly

follow

an

index)

as

well

as

the

costs

of

operating

a

fund

would

necessarily

contribute

to

differences

in

performance

results

and

limit

the

value

of

the

comparative

performance

information.

To

assist

the

Board

in

its

review

of

the

comparability

of

the

relative

performance,

the

Adviser

has

ranked

the

relevancy

of

the

peer

group

to

the

Funds

as

low,

medium

or

high.

The

secondary

market

trading

of

shares

of

the

Nuveen

closed-end

funds

also

continues

to

be

a

priority

for

the

Board

given

its

importance

to

shareholders,

and

therefore

the

Board

and/or

its

Closed-end

Fund

committee

reviews

certain

performance

data

reflecting,

among

other

things,

the

premiums

and

discounts

at

which

the

shares

of

the

Nuveen

closed-end

funds

have

traded

over

specified

periods

throughout

the

year.

In

its

review,

the

Board

considers,

among

other

things,

changes

to

investment

mandates

and

guidelines,

distribution

policies,

leverage

levels

and

types;

share

repurchases

and

similar

capital

market

actions;

and

effective

communications

programs

to

build

greater

awareness

and

deepen

understanding

of

closed-end

funds.

As

applicable,

the

Board

considered

the

impact

of

leverage

on

a

Nuveen

fund’s

performance.

The

Board

further

acknowledged

that

performance

results

should

include

the

distribution

yields

of

funds

that

seek

to

provide

income

as

part

of

their

investment

objective(s)

to

shareholders.

In

this

regard,

the

Board

considered

that

the

use

of

leverage

by

various

funds

may

have

detracted

from

total

return

performance

of

such

funds

over

various

periods

in

current

market

conditions,

but

the

leverage

also

was

accretive

in

helping

to

provide

income.

The

Board

also

evaluated

Nuveen

fund

performance

in

light

of

various

relevant

factors

which

may

include,

among

other

things,

general

market

conditions,

issuer-specific

information,

asset

class

information,

leverage

and

fund

cash

flows.

The

Board

acknowledged

that

long-term

performance

could

be

impacted

by

even

one

period

of

significant

outperformance

or

underperformance

and

that

a

single

investment

theme

could

disproportionately

affect

performance.

Further,

the

Board

recognized

that

the

market

and

economic

conditions

may

significantly

impact

a

fund’s

performance,

particularly

over

shorter

periods,

and

such

performance

may

be

more

reflective

of

such

economic

or

market

events

and

not

necessarily

reflective

of

management

skill.

Although

the

Board

reviews

short-,

intermediate-

and

longer-term

performance

data,

the

Board

recognized

that

longer

periods

of

performance

may

reflect

full

market

cycles.

In

relation

to

recent

general

market

conditions,

the

Board

had

recognized

the

general

market

volatility

and

underperformance

of

the

market

in

2022

in

considering

Nuveen

fund

performance.

The

Board

took

into

account

the

Adviser’s

assessment

of

a

fund’s

performance

during

the

recent

period

of

significant

market

volatility.

In

their

review

from

year

to

year,

the

Board

Members

consider

and

may

place

different

emphasis

on

the

relevant

information

in

light

of

changing

circumstances

in

market

and

economic

conditions.

In

evaluating

performance,

the

Board

focused

particular

attention

on

funds

with

less

favorable

performance

records.

However,

depending

on

the

facts

and

circumstances

including

any

differences

between

the

respective

fund

and

its

benchmark

and/or

Performance

Peer

Group,

the

Board

may

be

satisfied

with

a

fund’s

performance

notwithstanding

74

Annual

Investment

Management

Agreement

Approval

Process

(Unaudited)

(continued)

that

its

performance

may

be

below

that

of

its

benchmark

and/or

peer

group

for

certain

periods.

With

respect

to

any

funds

for

which

the

Board

has

identified

performance

issues,

the

Board

seeks

to

monitor

such

funds

closely

until

performance

improves,

discusses

with

the

Adviser

the

reasons

for

such

results,

considers

whether

any

steps

are

necessary

or

appropriate

to

address

such

issues,

and

reviews

the

results

of

any

steps

undertaken.

The

Board’s

determinations

with

respect

to

each

Fund

are

summarized

below.

For

Nuveen

Select

Maturities

Municipal

Fund

(the

“Select

Maturities

Fund”),

the

Board

noted

that

although

the

Fund’s

performance

was

below

the

performance

of

its

benchmark

for

the

one-year

periods

ended

December

31,

2022

and

March

31,

2023,

the

Fund

outperformed

its

benchmark

for

the

three-

and

five-year

periods

ended

December

31,

2022

and

March

31,

2023.

In

addition,

the

Fund

ranked

in

the

first

quartile

of

its

Performance

Peer

Group

for

the

one-

and

three-year

periods

and

second

quartile

for

the

five-year

periods

ended

December

31,

2022

and

March

31,

2023.

In

its

review,

the

Board

noted

that

the

Performance

Peer

Group

was

classified

as

low

for

relevancy.

On

the

basis

of

the

Board’s

ongoing

review

of

investment

performance

and

all

relevant

factors,

including

the

relative

market

conditions

during

certain

reporting

periods,

the

Fund’s

investment

objective(s)

and

management’s

discussion

of

performance,

the

Board

concluded

that

in

light

of

these

factors,

the

Fund’s

performance

supported

renewal

of

the

Advisory

Agreements.

For

Nuveen

Select

Tax-Free

Income

Portfolio

(the

“Select

Tax-Free

Income

Fund”),

the

Board

noted

that

although

the

Fund’s

performance

was

below

the

performance

of

its

benchmark

for

the

one-year

period

ended

December

31,

2022,

the

Fund

outperformed

its

benchmark

for

the

three-

and

five-year

periods

ended

December

31,

2022.

The

Fund

also

ranked

in

the

second

quartile

of

its

Performance

Peer

Group

for

the

one-

and

three-year

periods

ended

December 31,

2022

and

first

quartile

for

the

five-year

period

ended

December

31,

2022.

In

addition,

the

Fund

outperformed

its

benchmark

for

the

one-,

three-

and

five-year

periods

ended

March

31,

2023

and

ranked

in

the

second

quartile

of

its

Performance

Peer

Group

for

the

one-

and

three-year

periods

ended

March

31,

2023

and

first

quartile

for

the

five-year

period

ended

March

31,

2023.

In

its

review,

the

Board

noted

that

the

Performance

Peer

Group

was

classified

as

low

for

relevancy.

On

the

basis

of

the

Board’s

ongoing

review

of

investment

performance

and

all

relevant

factors,

including

the

relative

market

conditions

during

certain

reporting

periods,

the

Fund’s

investment

objective(s)

and

management’s

discussion

of

performance,

the

Board

concluded

that

in

light

of

these

factors,

the

Fund’s

performance

supported

renewal

of

the

Advisory

Agreements.

C.

Fees,

Expenses

and

Profitability

1.

Fees

and

Expenses

As

part

of

its

annual

review,

the

Board

generally

reviewed,

among

other

things,

with

respect

to

the

Nuveen

closed-end

funds,

the

contractual

management

fee

and

actual

management

fee

(i.e.,

the

management

fee

after

taking

into

consideration

fee

waivers

and/or

expense

reimbursements,

if

any)

paid

by

a

fund

to

the

Adviser

in

light

of

the

nature,

extent

and

quality

of

the

services

provided.

The

Board

also

considered

the

total

operating

expense

ratio

of

a

fund

(after

any

fee

waivers

and/or

expense

reimbursements).

More

specifically,

the

Independent

Board

Members

reviewed,

among

other

things,

each

Nuveen

closed-end

fund’s

actual

management

fee

rate

(after

fee

waivers

and/or

expense

reimbursements,

if

any)

and

net

total

expense

ratio

in

relation

to

those

of

a

comparable

universe

of

funds

(the

“Peer

Universe”)

established

by

Broadridge.

The

Independent

Board

Members

reviewed

the

methodology

Broadridge

employed

to

establish

its

Peer

Universe

and

recognized

that

differences

between

the

applicable

fund

and

its

respective

Peer

Universe

as

well

as

changes

to

the

composition

of

the

Peer

Universe

from

year

to

year

may

limit

some

of

the

value

of

the

comparative

data.

The

Independent

Board

Members

take

these

limitations

and

differences

into

account

when

reviewing

comparative

peer

data.

The

Independent

Board

Members

also

considered

a

fund’s

operating

expense

ratio

as

it

more

directly

reflected

the

shareholder’s

costs

in

investing

in

the

respective

fund.

In

their

review,

the

Independent

Board

Members

considered,

in

particular,

each

Nuveen

fund

with

a

net

total

expense

ratio

(excluding

investment-related

costs

of

leverage

for

closed-end

funds)

of

six

basis

points

or

higher

compared

to

that

of

its

peer

average

(each,

an

“Expense

Outlier

Fund”),

including

the

Select

Maturities

Fund,

and

an

analysis

as

to

the

factors

contributing

to

each

such

fund’s

higher

relative

net

total

expense

ratio.

In

addition,

although

the

Board

reviewed

a

fund’s

total

net

expenses

both

including

and

excluding

investment-related

expenses

(i.e.,

leverage

costs)

for

certain

of

the

closed-end

funds,

the

Board

recognized

that

leverage

expenses

will

vary

across

funds

and

in

comparison

to

peers

because

of

differences

in

the

forms

and

terms

of

leverage

employed

by

the

respective

fund.

Accordingly,

in

reviewing

the

comparative

data

between

a

fund

and

its

peers,

the

Board

generally

considered

the

fund’s

net

total

expense

ratio

and

fees

(excluding

leverage

costs

and

leveraged

assets

for

the

closed-end

funds)

to

be

higher

if

they

were

over

10

basis

points

higher,

slightly

higher

if

they

were

6

to

10

basis

points

higher,

in

line

if

they

were

within

approximately

5

basis

points

higher

than

the

peer

average

and

below

if

they

were

below

the

peer

average

of

the

Peer

Universe.

The

Independent

Board

Members

also

considered,

in

relevant

part,

a

Nuveen

fund’s

management

fee

and

net

total

expense

ratio

in

light

of

its

performance

history,

including

reviewing

certain

funds

identified

by

the

Adviser

and/or

the

Board

as

having

a

higher

net

total

expense

ratio

or

management

fee

compared

to

their

respective

peers

coupled

with

experiencing

periods

of

challenged

performance

and

considering

the

reasons

for

such

comparative

positions.

In

addition,

with

respect

to

closed-end

funds

that

utilize

leverage,

the

Independent

Board

Members

recognized

that

certain

assets

attributable

to

a

fund’s

use

of

leverage

may

be

included

in

the

amount

of

assets

upon

which

the

advisory

fee

or

sub-advisory

fee

is

calculated.

The

Independent

Board

Members

acknowledged

the

fact

that

a

decision

to

employ

leverage

or

increase

a

fund’s

leverage

which

has

the

effect,

all

other

things

being

equal,

of

increasing

the

assets

upon

which

an

advisory

or

sub-

advisory

fee

is

based

(and,

in

turn,

increasing

the

Adviser’s

and

applicable

sub-adviser’s

management

fees),

means

that

the

Adviser

and

applicable

sub-adviser

may

have

a

conflict

of

interest

in

determining

whether

to

use

or

increase

leverage.

The

Independent

Board

Members

recognized,

however,

that

the

Adviser

and

sub-advisers

would

seek

to

manage

the

potential

conflict

by

recommending

to

the

Board

to

leverage

the

applicable

fund

or

increase

such

leverage

when

the

Adviser

and/or

sub-adviser,

as

applicable,

has

determined

that

such

action

would

be

in

the

best

interests

of

the

respective

fund

and

its

common

shareholders

and

by

periodically

reviewing

with

the

Board

the

fund’s

performance

and

the

impact

of

the

use

of

leverage

on

that

performance.

75

In

their

review

of

the

fee

arrangements

for

the

Nuveen

funds,

the

Independent

Board

Members

also

considered

the

management

fee

schedules,

including

the

complex-wide

and

fund-level

breakpoint

schedules,

as

applicable.

The

Board

noted

that

across

the

Nuveen

fund

complex,

the

complex-wide

fee

breakpoints

reduced

fees

by

approximately

$62.4

million

and

fund-level

breakpoints

reduced

fees

by

approximately

$76.1

million

in

2022.

With

respect

to

the

Sub-Adviser,

the

Board

also

considered,

among

other

things,

the

sub-advisory

fee

schedule

paid

to

the

Sub-Adviser

in

light

of

the

sub-advisory

services

provided

to

the

respective

Fund

and

comparative

data

of

the

fees

the

Sub-Adviser

charges

to

other

clients,

if

any.

In

its

review,

the

Board

recognized

that

the

compensation

paid

to

the

Sub-Adviser

is

the

responsibility

of

the

Adviser,

not

the

Funds.

The

Independent

Board

Members

noted

that

(a)

the

Select

Tax-Free

Income

Fund

had

an

actual

management

fee

and

a

net

total

expense

ratio

that

were

below

the

respective

peer

averages;

and

(b)

the

Select

Maturities

Fund

had

an

actual

management

fee

and

a

net

total

expense

ratio

that

were

higher

than

the

respective

peer

averages.

The

Independent

Board

Members

noted

that

the

Select

Maturities

Fund’s

net

total

expense

ratio

was

higher

than

the

average

of

the

Peer

Universe

primarily

due

to

the

odd

composition

of

the

Peer

Universe

which

contained

only

one

other

fund,

which

was

another

Nuveen

fund.

Based

on

its

review

of

the

information

provided,

the

Board

determined

that

each

Fund’s

management

fees

(as

applicable)

to

a

Fund

Adviser

were

reasonable

in

light

of

the

nature,

extent

and

quality

of

services

provided

to

the

Fund.

2.

Comparisons

with

the

Fees

of

Other

Clients

In

evaluating

the

appropriateness

of

fees,

the

Board

also

considered

information

regarding

the

fee

rates

the

respective

Fund

Advisers

charged

to

certain

other

types

of

clients

and

the

type

of

services

provided

to

these

other

clients.

With

respect

to

the

municipal

Nuveen

funds,

such

other

clients

may

include

retail

and

institutional

municipal

managed

accounts

sub-advised

by

the

Sub-Adviser,

municipal

exchange-traded

funds

(“ETFs”)

sub-advised

by

the

Sub-Adviser

that

are

offered

by

another

fund

complex,

municipal

managed

accounts

offered

by

an

unaffiliated

adviser

and

certain

municipal

private

limited

partnerships

offered

by

Nuveen.

The

Board

reviewed,

among

other

things,

the

fee

range

and

average

fee

of

municipal

retail

advisory

accounts

and

municipal

institutional

accounts,

the

sub-advisory

fee

the

Sub-Adviser

received

for

serving

as

sub-adviser

to

certain

municipal

ETFs

offered

outside

the

Nuveen

family

and

the

management

fee

rates

paid

by

the

municipal

private

limited

partnerships

operated

by

Nuveen.

In

considering

the

comparative

fee

data,

the

Board

recognized

that

differences,

including

but

not

limited

to,

the

amount,

type

and

level

of

services

provided

by

the

Adviser

to

the

Nuveen

funds

compared

to

that

provided

to

other

clients

as

well

as

differences

in

investment

policies;

eligible

portfolio

assets

and

the

manner

of

managing

such

assets;

product

structure;

investor

profiles;

account

sizes;

and

regulatory

requirements

contribute

to

the

variations

in

the

fee

schedules.

The

Board

acknowledged

the

wide

range

of

services

in

addition

to

investment

management

that

the

Adviser

had

provided

to

the

Nuveen

funds

compared

to

other

types

of

clients

as

well

as

the

increased

entrepreneurial,

legal

and

regulatory

risks

that

the

Adviser

incurs

in

sponsoring

and

managing

the

Nuveen

funds.

In

general,

higher

fee

levels

reflect

higher

levels

of

service

provided

by

the

Adviser,

increased

investment

management

complexity,

greater

product

management

requirements,

and

higher

levels

of

business

risk

or

some

combination

of

these

factors.

The

Board

further

considered

that

the

Sub-Adviser’s

fee

is

essentially

for

portfolio

management

services

and

therefore

more

comparable

to

the

fees

it

receives

for

retail

wrap

accounts

and

other

external

sub-advisory

mandates.

The

Board

concluded

the

varying

levels

of

fees

were

justified

given,

among

other

things,

the

more

extensive

services,

regulatory

requirements

and

legal

liabilities,

and

the

entrepreneurial,

legal

and

regulatory

risks

incurred

in

sponsoring

and

advising

a

registered

investment

company

compared

to

that

required

in

advising

other

types

of

clients.

3.

Profitability

of

Fund

Advisers

In

their

review,

the

Independent

Board

Members

considered

estimated

profitability

information

of

Nuveen

as

a

result

of

its

advisory

services

to

the

Nuveen

funds

as

well

as

profitability

data

of

other

publicly

traded

asset

management

firms.

Such

profitability

information

included,

among

other

things,

gross

and

net

revenue

margins

(excluding

distribution)

of

Nuveen

Investments,

Inc.

(“Nuveen

Investments”)

for

services

to

the

Nuveen

funds

on

a

pre-tax

and

after-tax

basis

for

the

2022

and

2021

calendar

years

as

well

as

the

revenues

earned

(less

any

expense

reimbursements/fee

waivers)

and

expenses

incurred

by

Nuveen

Investments

for

its

advisory

activities

to

the

Nuveen

funds

(excluding

distribution

and

certain

other

expenses)

for

the

2022

and

2021

calendar

years.

The

Independent

Board

Members

also

considered

a

summary

of

some

of

the

key

factors

that

impacted

Nuveen’s

profitability

in

2022.

In

addition,

the

Board

reviewed

the

revenues,

expenses

and

operating

margin

(pre-

and

after-tax)

the

Adviser

derived

from

its

ETF

product

line

for

the

2022

and

2021

calendar

years.

In

developing

the

profitability

data

of

the

Adviser

for

its

advisory

services

to

the

Nuveen

funds,

the

Independent

Board

Members

recognized

the

subjective

nature

of

calculating

profitability

as

the

information

is

not

audited

and

is

necessarily

dependent

on

cost

allocation

methodologies

to

allocate

expenses

throughout

the

complex

and

among

the

various

advisory

products.

Given

there

is

no

perfect

expense

allocation

methodology

and

that

other

reasonable

and

valid

allocation

methodologies

could

be

employed

and

could

lead

to

significantly

different

results,

the

Board

reviewed,

among

other

things,

a

description

of

the

cost

allocation

methodologies

employed

to

develop

the

financial

information,

a

summary

of

the

history

of

changes

to

the

methodology

over

the

years

from

2010

through

2022,

and

a

historical

expense

analysis

of

Nuveen

Investments’

revenues,

expenses

and

pre-tax

net

revenue

margins

derived

from

its

advisory

services

to

the

Nuveen

funds

(excluding

distribution)

for

the

calendar

years

from

2017

through

2022.

The

Board

had

also

appointed

four

Independent

Board

Members

to

serve

as

the

Board’s

liaisons,

with

the

assistance

of

independent

counsel,

to

meet

with

representatives

of

the

Adviser

and

review

the

development

of

the

profitability

data

and

to

report

to

the

full

Board.

(continued)

In

addition,

the

Board

considered

certain

comparative

operating

margin

data.

In

this

regard,

the

Board

reviewed

the

operating

margins

of

Nuveen

Investments

compared

to

the

adjusted

operating

margins

of

a

peer

group

of

asset

management

firms

with

publicly

available

data

and

the

most

comparable

assets

under

management

(based

on

asset

size

and

asset

composition)

to

Nuveen.

The

Board

recognized

that

the

operating

margins

of

the

peers

were

adjusted

generally

to

address

that

certain

services

provided

by

the

peers

were

not

provided

by

Nuveen.

The

Board

also

reviewed,

among

other

things,

the

net

revenue

margins

(pre-tax)

of

Nuveen

Investments

on

a

company-wide

basis

and

the

net

revenue

margins

(pre-tax)

of

Nuveen

Investments

derived

from

its

services

to

the

Nuveen

funds

only

(including

and

excluding

distribution)

compared

to

the

adjusted

operating

margins

of

the

peer

group

for

each

calendar

year

from

2012

to

2022.

Although

the

total

company

operating

margins

of

Nuveen

Investments

were

in

the

bottom

half

of

the

peer

group

range

for

2022

and

2021,

the

Independent

Board

Members

recognized

the

limitations

of

the

comparative

data

given

that

peer

data

is

not

generally

public

and

the

calculation

of

profitability

is

subjective

and

affected

by

numerous

factors

(such

as

types

of

funds

a

peer

manages,

its

business

mix,

its

cost

of

capital,

the

numerous

assumptions

underlying

the

methodology

used

to

allocate

expenses

and

other

factors)

that

can

have

a

significant

impact

on

the

results.

Aside

from

Nuveen’s

profitability,

the

Board

recognized

that

the

Adviser

is

a

subsidiary

of

Nuveen,

LLC,

the

investment

management

arm

of

Teachers

Insurance

and

Annuity

Association

of

America

(“TIAA”).

Accordingly,

the

Board

also

reviewed

a

balance

sheet

for

TIAA

reflecting

its

assets,

liabilities

and

capital

and

contingency

reserves

for

the

2022

and

2021

calendar

years

to

consider

the

financial

strength

of

TIAA.

The

Board

recognized

the

benefit

of

an

investment

adviser

and

its

parent

with

significant

resources,

particularly

during

periods

of

market

volatility.

The

Board

also

noted

the

reinvestments

Nuveen,

its

parent

and/or

other

affiliates

made

into

its

business

through,

among

other

things,

the

investment

of

seed

capital

in

certain

Nuveen

funds

and

continued

investments

in

enhancements

to

technological

capabilities.

In

addition

to

Nuveen,

the

Independent

Board

Members

considered

the

profitability

of

the

Sub-Adviser

from

its

relationships

with

the

respective

Nuveen

funds.

In

this

regard,

the

Independent

Board

Members

reviewed,

among

other

things,

the

Sub-Adviser’s

revenues,

expenses

and

net

revenue

margins

(pre-

and

after-tax)

for

its

advisory

activities

to

the

respective

Nuveen

funds

for

the

calendar

years

ended

December

31,

2022

and

December

31,

2021.

The

Independent

Board

Members

also

reviewed

a

profitability

analysis

reflecting

the

revenues,

expenses

and

revenue

margin

(pre-

and

after-tax)

by

asset

type

for

the

Sub-Adviser

for

the

calendar

years

ending

December

31,

2022

and

December

31,

2021.

In

evaluating

the

reasonableness

of

the

compensation,

the

Independent

Board

Members

also

considered

any

other

ancillary

benefits

derived

by

the

respective

Fund

Adviser

from

its

relationship

with

the

Nuveen

funds

as

discussed

in

further

detail

below.

Based

on

a

consideration

of

all

the

information

provided,

the

Board

noted

that

Nuveen’s

and

the

Sub-Adviser’s

level

of

profitability

was

acceptable

and

not

unreasonable

in

light

of

the

services

provided.

D.

Economies

of

Scale

and

Whether

Fee

Levels

Reflect

These

Economies

of

Scale

The

Board

considered

whether

there

have

been

economies

of

scale

with

respect

to

the

management

of

the

Nuveen

funds,

whether

these

economies

of

scale

have

been

appropriately

shared

with

the

funds

and

whether

there

is

potential

for

realization

of

further

economies

of

scale.

Although

the

Board

recognized

that

economies

of

scale

are

difficult

to

measure

with

any

precision

and

certain

expenses

may

not

decline

with

a

rise

in

assets,

the

Board

considered

that

Nuveen

shares

the

benefits

of

economies

of

scale,

if

any,

in

a

number

of

ways

including

through

the

use

of

breakpoints

in

the

management

fee

schedule,

fee

waivers

and/or

expense

limitations,

the

pricing

of

funds

at

scale

at

inception

and

investments

in

Nuveen’s

business

which

can

enhance

the

services

provided

to

the

funds

for

the

fees

paid.

In

this

regard,

the

Board

recognized

that

the

management

fee

of

the

Adviser

is

generally

comprised

of

a

fund-level

component

and

a

complex-level

component

each

with

its

own

breakpoint

schedule,

subject

to

certain

exceptions.

The

Board

reviewed

the

fund-level

and

complex-level

fee

schedules.

With

this

structure,

the

Board

noted

that

the

complex-level

breakpoint

schedule

is

designed

to

deliver

the

benefits

of

economies

of

scale

to

shareholders

when

the

eligible

assets

in

the

complex

pass

certain

thresholds

even

if

the

assets

of

a

particular

fund

are

unchanged

or

have

declined,

and

the

fund-level

breakpoint

schedules

are

designed

to

share

economies

of

scale

with

shareholders

if

the

particular

fund

grows.

The

Board

noted,

however,

that

although

closed-end

funds

may

make

additional

share

offerings

from

time

to

time,

the

closed-end

funds

have

a

more

limited

ability

to

increase

their

assets

because

the

growth

of

their

assets

will

occur

primarily

from

the

appreciation

of

their

investment

portfolios.

As

noted

above,

the

Independent

Board

Members

also

recognized

the

continued

reinvestment

in

Nuveen’s

business

to

enhance

its

capabilities

and

services

to

the

benefit

of

its

various

clients.

The

Board

understood

that

many

of

these

investments

in

the

Nuveen

business

were

not

specific

to

individual

Nuveen

funds

but

rather

incurred

across

of

a

variety

of

products

and

services

pursuant

to

which

the

family

of

Nuveen

funds

as

a

whole

may

benefit.

In

addition,

the

Board

also

considered

that

Nuveen

has

provided,

without

raising

advisory

fees

to

the

Nuveen

funds,

certain

additional

services,

including,

but

not

limited

to,

services

required

by

new

regulations

and

regulatory

interpretations,

and

this

was

also

a

means

of

sharing

economies

of

scale

with

the

funds

and

their

shareholders.

Based

on

its

review,

the

Board

was

satisfied

that

the

current

fee

arrangements

together

with

the

reinvestment

in

Nuveen’s

business

appropriately

shared

any

economies

of

scale

with

shareholders.

E.

Indirect

Benefits

The

Independent

Board

Members

received

and

considered

information

regarding

other

benefits

the

respective

Fund

Adviser

or

its

affiliates

may

receive

as

a

result

of

their

relationship

with

the

Nuveen

funds.

The

Board

acknowledged

that

an

affiliate

of

the

Adviser

may

receive

compensation

for

serving

as

a

co-manager

in

the

initial

public

offerings

of

new

Nuveen

closed-end

funds

(if

any)

and

for

serving

as

an

underwriter

on

shelf

offerings

of

existing

Nuveen

closed-end

funds

and

reviewed

the

amounts

paid

for

such

services,

if

any,

in

2021

and

2022.

In

addition,

the

Independent

Board

Members

noted

that

the

various

sub-advisers

to

the

Nuveen

funds

do

not

generally

benefit

from

soft

dollar

arrangements

with

respect

to

Nuveen

fund

portfolio

transactions.

77

Based

on

its

review,

the

Board

concluded

that

any

indirect

benefits

received

by

a

Fund

Adviser

as

a

result

of

its

relationship

with

the

Funds

were

reasonable

in

light

of

the

services

provided.

F.

Other

Considerations

The

Independent

Board

Members

did

not

identify

any

single

factor

discussed

previously

as

all-important

or

controlling.

The

Independent

Board

Members

concluded

that

the

terms

of

each

Advisory

Agreement

were

reasonable,

that

the

respective

Fund

Adviser’s

fees

were

reasonable

in

light

of

the

services

provided

to

each

Fund

and

that

the

Advisory

Agreements

be

renewed

for

an

additional

one-year

period.
